To all whom it may concern:

Be it known that JOHN DAMM, a citizen of the United States of America, residing` at Brockton, in the county of Schuylkill and State of Pennsylvania, has invented new and useful Improvements in Condensers, of which the following is a specification.

The object ,of the invention is to provide a simple and eiiicient means for condensingy the exhaust steam used in the operation of mine pump engines, utilizing a portion of the water supplied by the pump for facilitating` the condensation of the steam and with this object in view the invention consists in a construction and combination of parts oi:V

which a preferred embodiment is shown in the drawing,rwhere1n: f

Figure 1 is a general view of the appa' ratus.

Figure 2 is a sectional view of the dome and condenser casing in which the same is housed.

Figure 3 is a sectional view of the mud` hopper.`

Figure 4 is a` horizontal sectional view on the plane indicated by the line lr-4 of Figure Figure 5 is afvertical sectional view on the plane indicated by the line 5 5 of Figure 2. c

The exhaust pipe 10 from the engine leads to the ycondenser casing 11 and discharges into a dome 12 housed within the casing and provided preferably in the wall opposite to the entrance of the exhaust pipe, with discharge perforations 13 formed in a wall sists of an inner glass or non-corrosive lin` ing 22 disposed in alprotecting vshell 23er brass which constitutes a housing.

The water to supply the spray nozzle and the discharge nozzle is conveyed to the mud hopper or mud drum 24 by the pump discharge pipe 25 having a suitablecontrolling valve 26, said hopper having a blowout pipe 27 iitted with a controlling valve 28, and byv the closing of the latter and the adjustment of the valve 26, the desired pressure may be Vsecured in the mud hopperv or drum underl the further control of the valves 2O and 21v denser casingwhere it is encountered by the discharge from the nozzle 17 to complete the condensation, said discharge nozzle 17 by reason of being directed toward theoutlet 19 serving to create a tension or suction due to the rarification ofthe air in the condenser casing to insure the efective induction of the exhaust steam to the dome.

A mud screen 29 is located within themud hopper or drum in communication with thewater discharge pipe 16 to prevent dirt or foreign matter from thefpump from entering thek condenser, and obviously from time to time the blow-ofi` valve 28 may be yopened to remove accumulations from the interior of the mud hopper.

What is claimed is:

1. A condenser for mine pump engines and the like having a condenser casing provided with an enclosedsteam dome for the reception of the exhaust steam, said steam dome eoI having discharge perforations in an ,exposed Wall thereof, a pump fed spray nozzle for discharging water in a path intersecting that of discharge from said steam dome, and a suction-inducing discharge nozzle located within the condenser 'casing and directed toward the outlet thereof.

2. A condenser for mine pump engines and the like having a condenser casing provided with a depending tapered or reduced portion terminating in an outlet, va steamV f dome housed Within the casing and in oonifed discharge nozzle located in the vieduoe;

munioation WithV the engine exhaust, seid portion ofthe casing and directed toward dome being provided With discharge perfotheoutlet thereof. 10 rations incommunieation With the interior In testimony whereof he eiiixes his sig-l O vthe easing, ef pump fed spray nozzle lfor nature. i i discharging e spray in a path intersecting Y the discharge from said dome,v and a 'puin'p' V` Y Y Y l Y JOHN DAMM.
